T. KOBAYASHI THERMATOLOGIC ELEQTRODE Filed spt. 2,- 1924 Tawau/06H1 Kas/1 m sw.


Patented Feb. 16, 1926.


rsUnUKrorrr KOBAYAsrrI, or Los aNGnLEsoALIroRNIA.

THnnMnroLoGrc Ennornorm, p i e Application filed. September To ZZ whom t may concern:

Be it known that I, TsUnUKroHI loeArAsrrr, a subject of the Emperor of Japan, residing in the lcity and county of Los Angeles and State of California, haver invented a new and useful Thermatologic Electrode, of which the following is a specilication.

The present invention relates to a device Iadapted for the application of electric eurrent for therapeutic effects, and embodies means for applying heat and moisture for stimulating the circulation, and other healing effects, conjointly with the application of an electric current.

Another object is to provide means for the Vapplication of medicative fluids. conjointly with electrical treatments.

Another object is to'provide an electrode having a detachable contact element-whereby the same may be readily renewed or replaced for sanitary purposes.

Another object is to provide an electrode embodying a combination of elements adapted for a uniform and continuous application of electric current in therapeutic treatments.

lllith the ordinary electrodes, the electrical effects are intermittent and irregular, for, if the electrodes are dipped in a fluid, the current is supernormal when the electrodes are moist, and subnormal when the electrodes become dry.

To avoid these objections, I have provided an improved form of electrode, capable of holding a quantity of fluid, and, if such fluid be heated, capable of retaining a uniform temperature for some time and capable of maintaining` the contact element in a moist condition for a considerable time.

Various modifications may be made with! out departing` from the nature of the invention, which consists essentially of associating with faradic and gallvanic electrode elements, other elements adapted to contain a heated liquid, elements for maintaining the liquid in its heated condition, and a contact element adapted for distributing minute quantities of the liquid eonjointly with the application of the electric current.

ln the drawings: Figure 1 is a. sectional view of an electrode constructed in aceordance with my invention. Fig. 2 is a detail view of the Contact pad. Fig. 3 is a plan view of the contact .end .of the electrode, .showing in dotted lines, Ithe I'pins for retain- 2, 1924. Serial NO. 735,423.

ing the pad in` position. Fig. el. is a detail view of a binding post for attachment to an electric terminal wire. Fig. 5 is a perspective detail view of an inner container element. Fig. .6 is a perspective view of the electrode.

Referring to the drawings, the tubular casing 11', forms the body of the electrode, and is covered with a heat insulating jacket 12, preferably of asbestos, and an exterior' protecting jacket 13, preferably of rubber fabric. A cap 14C, forming one end of the electrode, is provided with a nozzle 15, for refilling purposes. A rubber plug 1G, serves as a closure for the nozzle. The cap 14 i's provided with two binding posts 17, to either of which an electric conductor-18, maybe connected. -Rods 19 extendlongitudinally .through the body and are connected to the inner retainer element 20, .which forms the opposite head ofthe body. The element 2O is provided with a central portion Q1, proj ecting axially and longitudinally within the body, and provided with minute apertures 22 and 23. These apertures permit the Vliquid content 24 to percolate therethrough and to permeate the fabric filler 25, which is preferably of'asbestos. The contact ele ment 26, ,consists of a `pad'of absorbent fiber, provided with a. coarse fabric cover 27. Silver pins 2S, extend through the edges of the fabric retainer 27, and through apertures 29, in the flange 30 which is integral with the inner retainer element 20. The cap 1%1, tubular body 11, and inner retainer element 20, are all silver, or preferably silverplated. Corrosion by the liquid content Q4, is therefore avoided. The edges of fabric element 27 areprotected by jackets 12 and 13.

"While but one electrode isshown, it is to be understood that in'use, two electrodes similar to Fig. 1 will be employed by the operator, each connected to an electrical con ductor of opposite polarity as required for electric treatments. f

i In use, the electrodes are first filled with warm or hot water of the desired temperature, or with a medicated liquid, and tlren the electrodes are applied for massaging the person treated in the ordinary manner. The liquid permeates the filler and the contact pad, an-d maintains the contact pad in a. moist condition. The application of the electric current, conjointly with application of heat,

is favorable for ozonizing minute quantities of the moisture, and thereby increases the therapeutic effects.

lVhile the eieinents shown and described are Well adapted to serve the purpose forA nation With a body and a liquid contentV therein, of a cap toriningthe upper eX-y treinity of the body, an inner container ineniber forming the opposite end ofthe body and extending axially therein, an absorbent liller i'oi' the inner container n'ielnber, said container member having a series `oi` ininute apertures, metal rods extending through they body and connecting the cap and inner container member, terininal bindingposts on said rods and lon the exteriorV of the cap, and a` contact pad ot absorbent material detachably secured to `the klower extremity of the body, and arranged in contact with the absorbent liller;r

2. In therinatologic electrode, the coin bination with nietal elements arranged for application of an electriccurren@of' container elements associated therewith, a'liquid content therein, an absorbent padinounted on the container elenients, an inner container extending Within the liquid container, an absorbent liller in the inner container and abutting against the absorbent pad, said inner container having a series of mi nute apertures to pass the liquid content to the filler, and eoncentrieally arranged heat insulating jackets encasing the container elements.

i -3. In autherinatologic electrode, the co1nbinationwith a liquid container including a tubular body, a cap forining one end, and an inner concentriccontainerl 'forming the oppositegend and having its inne-rl wall pierced with a Series ot minute apertures, ot an apertured flange integral with the innerl container, rods connecting the inner container and cap, binding posts on the exterior oit the cap and connected to said rods, a reiilling nozzle on the cap, a pluo' serving to close said nozzle, a liquid content' within the body, an absorbent liller for theI inner container, an absorbent Contact pad mountedv on the endet the body, a fabric cover for thecontact pad, and retaining pins extending through the fabric cov-er and the apertured liange to detachably secure the contact padin connection with the absorbent iiller and an operative positionl on the body.
